Can a resource be a set or structure?

Dear all,
     Can a resource be a structure (not a collection)? In OO model, there are atomic 
objects and structured objects. Can resources and blank nodes be structured object?
In fact, the real question is: waht resources and blank nodes are, proxies of something 
else or the representation of the things themselves?
     Why there is no explicit description about this in rdf specifications? Is the question too naive?

Best regards,
